There really is no rhyme or reason to the pricing, not just Celebrity either, but that is who I sail with. I looked at a 6 night March 2025 Eclipse cruise FLL to Labadee (not happening) Bimini and a few sea days, RS 2 pax, $11k. I also priced it as a solo because my husband may not be able to take this one, solo price $15k! For reference we are already booked on the March 22 TA following this cruise, which is why I was considering it, and the cost for both of us on the TA in RS is $13.2K. Needless to say, we will not be going on the earlier cruise.
